I love to write - it is a great source of reflection, especially as I continue to meet many new inspiring people.
Hundreds and thousands of young people around the world can break through and can make this a better world for all living things. Once young people know the problems and are empowered to act, they have great power to impact the world.
I am obstinate and I will not give in.
If you work hard and be persistent, you will achieve whatever you want to do.
The person who has the most influence on me is my mother. Think of life as a flight where we fly higher and higher. If I were a bird that needs feathers to fly higher, I would regard my mother as my strongest feather.
If you consciously say 'I won't do it!' to yourself, then you have a good chance that you won't.
Successful actors and actresses have to get themselves into their roles before acting. Therefore, you need to really care about what you are saying.
You have to really care about what you say. And if you don't, it will never come out quite right, unless you go into acting, in which case you have to act fast before you realize it is something which you do not believe in.
We are always talking about how we can get more environmental and humanitarian education. It is about listening to the voice of young people - how they feel, and what would be most meaningful for them.
If you educate women, family size tends to go down.
You can't do everything. You can't do health and forestry and agriculture. You've got to focus and do one or the other.
If you do microcredit with men, they tend to quickly drink it. They don't pay you back.
I wasn't trying to be a scientist. I only ever wanted to be a naturalist, like a David Attenborough.
I had this wonderful, supportive mother who didn't get mad because of all the earth mucking up my bed. She just said they'd die - they needed the earth.
Animals have personalities and minds and emotions.
If a chimp who has been abused horribly by humans can help a human friend in a time of need, how much more should we help the animals - and other people for that matter - in their time of need?
I want to change awareness.
At some point, my body will collapse. But I hope that my brain will still be working so that I can carry on with writing.
Every individual can make a difference every day by making conscious choices.
The problem of the chimps is that they can only sit and look. They can't discuss what they feel. All that feeling is trapped within each one.
I still think we are smart enough to not destroy planet Earth, our only home.
The chimps' way of aggression is quick and brutal. I compare them to gang attacks.
Being evil is something that only humans are capable of.
A chimp would never plan to pull another's nails out.
Chimps are brutal, and it is so deliberate. The males go out and get near the boundary of their territory. And they walk very silently trying hard not to make any noise. They will climb into a tree and stare out over hostile territory for hours. They are waiting for the right opportunity. And then they attack.
